Best Essential Oil Diffusers That Will Turn Your Home Into a SPA

Choosing an essential oil diffuser isn’t as simple as one would think. For one, there are a lot of products to choose from. And, if you weren’t aware of this yet, there isn’t a one-size-fits-all option. While there may be favorites like URPOWER, it doesn’t mean that it’s the best option for your needs, preferences, and purpose. Moreover, one diffuser isn’t exactly interchangeable with another.

Some diffusers are louder than others, some have brighter lights. Some diffusers are great for freshening up a room while others are perfect for clearing your sinuses. Clearly, it’s not a purchase that you can do willy-nilly. So, to help you out, we did a search on the best oil diffusers available today and chose our top 12 favorites.

Just one major complaint from some light-sensitive sleepers: the power button has a backlight that won’t turn off so it can be a problem if you like to sleep in total darkness.

How To Choose The Best Essential Oil Diffusers

When it comes to essential oil diffusers, it’s best to know exactly what’s on the market and how they work so you can make the right purchase. Some people aren’t aware that there are actually several types of diffusers available and they are defined by the way they diffuse oil.

The most popular type is the ultrasonic or humidifying diffuser. This type of diffuser makes use of electronic frequencies to vibrate a disk that is located just under the surface of the water. It vibrates so fast that the water and essential oil is transformed into vapor and dispersed into the air as fine mist. The ultrasonic vibrations (which it is named after) causes the essential oil to be broken down into microparticles that enable us to easily breathe in its therapeutic properties. Compared to other types of diffusers, ultrasonic diffusers use less oil and works much more quietly. However, it does not always produce a strong concentration and requires regular cleaning.

Nebulizers, another form of essential oil diffuser, works much like a perfume atomizer. It breaks down the essential oil into small particles without water. While it’s much more powerful than an ultrasonic one, it is also incredibly expensive to buy and use. You need a lot of oil to get it going. It’s also a lot noisier than other types of diffusers.

Heat diffusers used to be the popular one. Like the name implies, the diffuser makes use of heat to break down the oil into molecules. The problem with this type of diffuser is that heat can change the composition of the oil. Also, it’s not safe to leave the diffuser unattended for long.

Fan or evaporative diffusers utilizes the process of evaporation to spread the oil particles into the air. The fan causes oil on a pad or filter to evaporate more quickly and disperses it into the room. While this type of diffuser is much simpler to use and inexpensive, it doesn’t produce as much therapeutic benefit as other types. Also, the scent doesn’t last long in the air which will require you to place more drops of oil on the pad. More importantly, the noise produced by the fan can be offputting to light sleepers.

So, how do you select the perfect diffuser for you? Well, here are some things you’ll need to consider:

Area of Coverage

You need to measure the size of the room you’d like to use the diffuser in. A 100ml essential oil diffuser such as the URPOWER 2nd Version Essential Oil Diffuser is perfect for a regular-sized bedroom. The VicTsing 300ml Cool Mist Humidifier Ultrasonic Aroma Essential Oil Diffuser or the OliveTech 400ml Ultrasonic Cool Mist Humidifier, on the other hand, covers a much larger area (approximately 400 to 500 square feet).

Timer & Automatic Shutoff Feature

These are two very important features if you plan to leave your essential oil diffuser unattended. First off, you don’t want it to continue running even when the water’s already too low. It’s just not safe. Secondly, some people are really sensitive to the aroma of essential oils. Too much dispersed into the air can cause headaches. Leaving it on a timer ensures you get all the therapeutic benefits without any of the drawbacks. The InnoGear Aromatherapy Essential Oil Diffuser Portable Ultrasonic Diffuser and the TaoTronics 300ml Aromatherapy Diffuser with Wood Grain both have several timer options – 1 hour, 3 hours, 6 hours, and steady mode. They also have the automatic shutoff feature.

Run time

How long do you plan on having the diffuser running? If you want it to run the entire night while you’re sleeping, you’ll need to invest in a diffuser that has a large capacity such as the Essential Oil Diffuser 300mL Anjou Aromatherapy Diffuser which can run for 8 hours straight or the PureSpa Deluxe Ultrasonic Aromatherapy Oil Diffuser can run continuously for 10 hours which means that you’ll be able to wake up with the diffuser still running!


One huge drawback of ultrasonic diffusers is the need to clean it regularly. Otherwise, it won’t perform as effectively and will not last as long as it should. This means that you’ll have to choose a diffuser that’s easy to clean – no muss, no fuss. The URPOWER 2nd Version Essential Oil Diffuser, 100ml is one good example of an easy to clean diffuser. Just wipe it with a rag dipped in a water+bleach solution and it’s ready to use again.


Naturally, it all boils down to what you can afford. But don’t you worry. It won’t be too hard to find some that would fit in your budget because a lot of really good essential oil diffusers are actually affordable. Here are some that are under $40: Radha Beauty Aromatherapy Essential Oil Diffuser, Essential Oil Diffuser Riverock, ZAQ Noor Essential Oil Diffuser LiteMist Ultrasonic Aromatherapy With Ionizer and Color-Changing Light, and Essential Oil Diffuser 300mL Anjou Aromatherapy Diffuser.

Remember, when buying anything for yourself, always make sure you’re well-informed. It’s not just about the price or the product’s popularity. You should always ensure that it serves your purpose as well.
